A library-based bioinformatics services program*

Support for molecular biology researchers has been limited to traditional library resources and services in most academic health sciences libraries. The University of Washington Health Sciences Libraries have been providing specialized services to this user community since 1995. The library recruited a Ph.D. biologist to assess the molecular biological information needs of researchers and design strategies to enhance library resources and services. A survey of laboratory research groups identified areas of greatest need and led to the development of a three-pronged program: consultation, education, and resource development. Outcomes of this program include bioinformatics consultation services, library-based and graduate level courses, networking of sequence analysis tools, and a biological research Web site. Bioinformatics clients are drawn from diverse departments and include clinical researchers in need of tools that are not readily available outside of basic sciences laboratories. Evaluation and usage statistics indicate that researchers, regardless of departmental affiliation or position, require support to access molecular biology and genetics resources. Centralizing such services in the library is a natural synergy of interests and enhances the provision of traditional library resources. Successful implementation of a library-based bioinformatics program requires both subject-specific and library and information technology expertise.

Health sciences libraries in Kuwait: a study of their resources, facilities, and services

The purpose of this study was to examine the current status of health sciences libraries in Kuwait in terms of their staff, collections, facilities, use of information technology, information services, and cooperation. Seventeen libraries participated in the study. Results show that the majority of health sciences libraries were established during the 1980s. Their collections are relatively small. The majority of their staff is nonprofessional. The majority of libraries provide only basic information services. Cooperation among libraries is limited. Survey results also indicate that a significant number of health sciences libraries are not automated. Some recommendations for the improvement of existing resources, facilities, and services are made.

Structural organization of mouse peroxisome proliferator-activated receptor gamma (mPPAR gamma) gene: alternative promoter use and different splicing yield two mPPAR gamma isoforms.

To gain insight into the regulation of expression of peroxisome proliferator-activated receptor (PPAR) isoforms, we have determined the structural organization of the mouse PPAR gamma (mPPAR gamma) gene. This gene extends > 105 kb and gives rise to two mRNAs (mPPAR gamma 1 and mPPAR gamma 2) that differ at their 5' ends. The mPPAR gamma 2 cDNA encodes an additional 30 amino acids N-terminal to the first ATG codon of mPPAR gamma 1 and reveals a different 5' untranslated sequence. We show that mPPAR gamma 1 mRNA is encoded by eight exons, whereas the mPPAR gamma 2 mRNA is encoded by seven exons. Most of the 5' untranslated sequence of mPPAR gamma 1 mRNA is encoded by two exons, whereas the 5' untranslated sequence and the extra 30 N-terminal amino acids of mPPAR gamma 2 are encoded by one exon, which is located between the second and third exons coding for mPPAR gamma 1. The last six exons of mPPAR gamma gene code for identical sequences in mPPAR gamma 1 and mPPAR gamma 2 isoforms. The mPPAR gamma 1 and mPPAR gamma 2 isoforms are transcribed from different promoters. The mPPAR gamma gene has been mapped to chromosome 6 E3-F1 by in situ hybridization using a biotin-labeled probe. These results establish that at least one of the PPAR genes yields more than one protein product, similar to that encountered with retinoid X receptor and retinoic acid receptor genes. The existence of multiple PPAR isoforms transcribed from different promoters could increase the diversity of ligand and tissue-specific transcriptional responses.

Library of libraries: approach to synthetic combinatorial library design and screening of "pharmacophore" motifs.

Construction of synthetic combinatorial libraries is described that allows for the generation of a library of motifs rather than a library of compounds. Peptide libraries based on this strategy were synthesized and screened with model targets streptavidin and anti-beta-endorphin antibody. The screens resulted in observation of expected motifs providing evidence of the effectiveness of the suggested approach.
